MOSAIC WORK.

SPECIFICATION forming part of Letters Patent No. 365,908, dated July 5, 1887.

Application filed October 7, 1885. Serial No. 215,629. (No model.)

To all whom it may concern.

Be it k nowu that I, EVARISTE CHATAIN, of the city and county of San Francisco, State of California, have invented an Improvementin Mosaic XVork; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to certain improve-- ments in mosaic and other similar work.

It consisls of a combination of plain or col ored marble or rock, or other suitable substance, with a cement or a base within which the material may be held, the whole being shaped and polished to form tiles or mosaics.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure l is one view of my block or plate. Fig. 2 shows another arrangement. I

In the construction of blocks, plates, or pieces for ornamental or other uses I employ irregular pieces of plain or different colored marble, rock, or other substance, which may be sufficiently hard and durable for the purpose, and which will also receive a certain amount of polish. in cement, with a defined pattern, and the whole is subjected to a heavy pressure, which consolidates it. It is afterward removed and allowed to set or harden, after which it is pol ished upon the surface, so as to form a mosaic block, which is very ornamental and durable. In the formation of these blocks, plates, or other pieces I employ molds which may be made of iron or other suitable substance and have the interior of the shape which it is desired to give thefinished blocks. The marble, rock, or other material, which is broken into small pieces or irregular fragments, isthen placed in the mold, so as to conform to a defined pattern, and when these particles are properly placed and in sufficient quantity the cement, which has been mixed to the proper consistency in any known or desirable manner, is poured into the mold, filling it so as to give the proper thickness to the tile or plate which is being formed, the top is leveled off, and the block is subjected to'a heavy pressure, which has the effect to concentrate and consolidate it, so that it can be removed from the These particles are embeddedmold without waiting for it to set in the ordinary mauner. By this method I save a great deal of time, and the blocks may be quickly and accurately prepared. After being removed from the mold, they are allowed to set in the atmosphere about one day, after which they are immersed in water and allowed to remain several'd ays, when they will be in readiness for use. By thus eompressingthcblocks they may be made thinner, and they are harder and can be transported to any part of the world. \Vhen taken from the mold, the rock will all be found firmly embedded in the cement, so as to give a party-colored or other appearance. These blocks, disks, or plates are afterward ground off or polished, so that the whole surfaceof the material is perfectly level and smooth, or is otherwise shaped to suit the form which is being made, and it is then ready for use. The material thus may be made in a great variety of forms, either square, diamond, or polygonal shape for tiles, the faces being plain, ofone or more colors, or they may bedivided by lines of different colors into well-defined figures. It may also be used for wainscoting, niantels, or ehimney'pieces, for tables, vases, cemetery work, or other various ornamental articles.

It may be used in any place or manner where marble, granite, or cement is used.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The process herein described for making mosaic work, consisting, essentially, in placing in a suitable mold irregular pieces of marble, rock, 850., pouring cement in said mold to obtain the desired thickness of tile or plate, then consolidating the mass by subjecting it to great pressure, whereby the tile or plate may be removed from the mold before drying,

and finally polishing said plate or tile, sub- 1 stantially as specified.

In witness whereof I have hereunto set my hand.

EVARISTE CH ATAIN.
